JL4 EBCM Routing Diagram ABS Brake Module for Escalade Yukon Denali Tahoe Etc
I spent most of my weekend looking for this info so I wanted to repost it here in case anyone else ever needs it, hopefully it's easier to find. This is NOT available in any of the GM service manuals or thru GM at all from what I could find. I found lots of info on the 5 port ABS module, but nothing on the 6 port module. The module itself is not labeled either.
If you ever replace the ABS module (EBCM) or replace brake lines and need the routing diagram for the 6 ports/outlets (RPO Code JL4 Active Handling), here it is: Looking at the ports face on: Top row (Left Front)-(Right Front)-(Left Rear)-(Right Rear) Bottom row (Front Master Cyl (primary), closest to Power Brake Booster)-(Rear Master Cyl) I finally found the above info here: 2005 Yukon XL brake line diagram to ehcu - GMC Forums |

Rear brakes are normally fed from the front of the master cylinder Can anyone make this anymore confusing? Attached is a diagram. https://cimg6.ibsrv.net/gimg/www.per...6e3a962a44.png |

I believe you have the last 2 ports reversed.

im a little late to the game here. I, too, just went through finding the correct 6-port BPMV. I finally have one, however, i stripped the port of the last one i had. Does anyone know the port thread sizes?
